[From 9:28 a.m. ET]: Police started beating up journalists protesting outside the Press Syndicate in downtown Cairo. They beat up women journalists too who were screaming and crying for help. “Do not club women. Do not club women,” some of the men rushed to the police asking them not to target women. “You’ll make things worse if you use violence” many journalists were telling police officers outside the building.

In the industrial city of Mahala, police virtually cordoned off the city. My sources in the city tell me the police ordered early dismissal of textile factory workers to preempt any organized protests of workers after work. They also blocked all traffic to some streets leading to the city center square, Al-Shoon Sqaure.

The protests are not asking for anything specific this time. They want the government out. It is that general.

Based in Cairo, Mekay reports for Inter Press Service and other outlets.

[The Egyptian government has apparently block Twitter, Facebook (as of Wed. morn U.S. ET) and other internet tools, though apparently some people are able to get around such restrictions. Email from 8:45 a.m. ET:]

Downtown Cairo today remains in a state of high alert. There are many security forces and plainsclothed policemen visible on every street in the center of the city. There have been minor clashes with protesters in various parts of Cairo, as well as in Assiyut – a city to the south.

At the moment, security forces are cordoning off Tahrir Square. Private security guards in the immediate area claimed that they have heard through Central Security that clashes are expected later in the day.

More to come.
